Carrier KFAIF0101HWC Air Pressure Switch
The function of an air pressure type switch is to determine whether or not the main blower is running. A lot of switches are designed with a reset that is manual instead of automatic, which forces the system to be reset physically in order for the HVAC system to continue running. This is one of many other aspects of the whole safety system that is intended to stop injuries or explosions.
Symptoms to Look for when the System Pressure Switch is Beginning to Fail
- HVAC system is unable to function.
- Inaccurate voltage range being used by the switch.
- The proper temperature indoors is almost never fully achieved.
